IMPROVEMENT IN SKVLlGHT-BARS.

Specification forming part of Letters Patent No. 147,130, datd February3, 1874; application filed November 6, 1873.

CASE B.

To all whom it may concern:

Be it known that I, GEORGE HAYES, of the city, county, and State of NewYork, have invented a certain new and useful Improvement in Skylights,of which the following is a specilication:

'This invention relates to improvements in means for supporting andsecuring the `glass plates of skylights; and it consists in theeinployment of supporting-bars, which are Vcomposed of a single piece ofsheet metal, formed with gutters at their lower ends, and with shouldersat their upper ends for-supporting the glass plates, the same beingretained in position by means of a cap-piece, which may be the uppertermination of a stil-fening-plate inserted into a continuous channel ortrough, form ed by bending the supporting-bar into the required shape;or said trough may be omitted,

'and the glass-retaining device be applied to the top ofthe bar.

In the accompanying drawing', Figures l and 2 are transverse sections ofthe supportingbar, with means for holding the glass plates in position.

I propose to lessen the cost of inaiuiiacture, and also the weight,ofthe bars A, whieheomprise the frame of a skylight, by making the sameof a sheet-metal plate, which is bent in such a manner as to formvertical side walls, the lower ends of which are bent in an outward andupward direction, so as to constitute gutters a2, which are designed toserve as receptacles for condensed vapors and rain. The top of the bar,or the horizontal portion intervening between the side walls of thesame, is made level or hat, as shown at a a, so as to form shoulders forsupporting the ends of two adjacent glass sections, D, and the cent alportion of the bar A being depressed orbent so as to form a continuouschannel or trough, el, as shown in Figs. 1 and 2, the glass-supportingshoulders a a being located at both sides of said trough. The glassplates, which rest upon the supporting-bar, are secured in position bymeans of a fastening device, which is designated by letters O in thevarious iigures. rlhe portion of the trough or channel al is to receivea strengthening or stiftening plate, B, and also to retain the lowerportion of a pair of fastening-plates, C, the upper ends of which arecapable of being turned down upon the ends of the glass plates D forsecuring the same in position, as shown in Fig. l. Instead of the solidstitening-plate for strengthening the glass -supporting bar, I mayemploy, as shown in Fig. 2, a doubled plate, C, or a pair of connectedplates, the upper ends of which can be turned down upon the glass, saidplate serving, in this instance, both as a stiii'ening medium and as aglass-retaining device.

The present invention is specially designed to furnish aglass-supporting bar which isl light and simple in construction, andeasily manufactured at a comparatively small cost.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a skylight, a glass-supporting bar, A, constructed of a single pieceof metal bent into shape to formatrough, al, base gutter or glitters a2,and top glass-supporting shoulders a, combined with a suitableglass-retaining device, substantially as described.
